One of the funniest calls I ever had was a very sinsere lady who called from a jurisdiction surrounding the airport, to tell us that see saw a suitcase fall off of an airplane that was nearing the airport. She was quite concerned that the traveler who lost their luggage would be distraught and wanted to leave her number for them to call so she could tell them where she thought it was.
Little did she know that the plane was about to land in an ALERT II status because one of the engines had fallen off the plane. Later they found the engine cowling right where she said it would be. Some people just want to helpful. I love that!
